` IMPROVEMENT IN BRICK AND SOAP PRESSES.

Specification forming part of Letters Patent No. 164,997, dated J une29, 1875; application led March 23, 1875.

To all whom it may concern Be it known that I, JACOB H. HEARN, ofMarshalltown, in the county of Marshall and State of Iowa, have inventedan Improved Brick and Soap Pressing Machine, of which the following is aspecification My invention consists in mounting and combining a press,and a table carrying molds, in such a manner that the reciprocatingmotion of the plunger will automatically and alternately rotate, andhold .and lock the table, at the precise points of time requiredtosubject the substance in the molds to the action of the plunger all ashereinafter fully set forth.

Figure l of my drawing is a perspective view, illustrating theconstruction and operation of my invention. Fig. 2 is a rear elevationof the same.

A A represents the base, in the form of a suitable frame-work. B is avertical post, rigidly secured to the base A, to support the press andits operative mechanism. C is an arm, extending at right angles from thepost B. D is a crank-wheel, which has its bearing in the end of thearm'C. E is a belt-wheel, or suitable driving-wheel, rigidly lixed onthe shaft of the crank-wheel D. a c lis a togglejoint, pivoted at itstop to the post B, and at its bottom to the press. b is a horizontallink, connecting the crank-wheel D with the togglejoint a a. G is theplunger, mounted in bearings projecting from the post B. H is a rack--bearer, rigidly attached to the plunger G. c is a vertical rack,attached to the lower end of the bearer H. d is a gear-Wheel or sector,loose upon the shaft g, which has its bearings in the :frame A. J is abevel-gear wheel, rigid on the horizontal shaft g. K is a pinion,matching and engaging the wheel J, rigidly iixed on the lower end of thevertical shaft L, which has its bearings in the frame A. M is therotating table, rigidly fixed to the top of the shaft L. l 2 3 4 aremortises through the table, in which suitable molds are carried andoperated. N is an inclined pla-ne, secured tothe frame A, underneath thetable M in such a manner that it will successively lift the molds in themortises l 2 3 4 as the table makes quarter revolutions, simultaneouslywith each upward movement of the press G. It is a cam on the rack-bearerH. m is a springlatch, pivoted to the frame A in such position relativeto the rotating table M that the latch h will engage notches in the edgeof the table, and in time with the mold-apertures l 2 3 4.

In the practical operation of my press any suitable power may be appliedto operate the drivin gwheel E, and thereby rotate the crankwheel D, andcommunicate an up-and-down motion to the press G, through the medium ofthe horizontal link b and toggle-joint c a. The press G, carrying therack c, on the bearer H, at each upward movement causes the rack c toengage the toothed sector d, which is loose on the horizontal shaft g. Asuitable clutch or ratchet on the side of the sector d causes the sectorto lock to the shaft g, and actuate the bevel-gear J K, and the verticalshaft L, and thereby cause the table M to make a quarter revolution.Thecam h, on the rack-bearer H, in its upward movements engages thepivoted spring-latch m, and frees the latch from the table, to allow thetable to move. Y

The molds in the apertures 1 2 3 4 can be lled and emptied successivelyby attendants.

During each downward movement of the press the latch m locks and holdsthe table M stationary, and the press engages the mold immediatelyunderneath, and compresses the contents of the mold. The upward movementof the press frees the table, and moves it sufficiently to bring asuccessive mold into proper position for its next downward move. lhesimultaneous movements of the press and table thus produced furnishes anew and convenient means of compressing clay, soap, and other plasticsubstances. Y

I am aware that in the construction of my press I employ commonmechanism and common devices, but my manner of arranging and combiningthe various parts to make the vertical plungerkG and the horizontalrotating table M co-operate to accomplish the results contemplatedproduces a new and useful machine.

I claim as my inventionl. The combination of frame A, post B, arm C,wheels D and E, connecting-link b, toggle-joint a a, and plunger G, whenarranged substantially as and for the purposes tially as and for thepurposes shown and deI shown and described. l d scribed.
